Analogue SDR modules for band shifting and power boosting of WiFi and LTE modems

Doodle Labs’ family of Band Shifters are analogue SDR modules to enable LTE and Wi-Fi modems to operate on a different frequency bands. They provide flexibility to system integrators looking to deploy their existing wireless modems at special frequency bands to expand the market opportunities.

The Band Shifters are in-line module placed between the radio modem and the antenna. Doodle Labs Prism® frequency shifting technology helps achieve the use of state-of-the-art COFDM/MIMO performance in any frequency band. Additionally, the Band Shifters amplify the Tx power and Rx gain to increase the wireless range. A large family of form factor compatibile modules in the 100 MHz – 6 GHz range means a simple swap of the Band Shifter module to switch to a different band to meet customer’s requirements in any market or country.
